I just saw this on Amazon.co.uk and am busy doing my happy dance. Reviews are lifeblood to authors and a huge boost when someone has obviously enjoyed a series. I hope the reader enjoys the fourth book, Staff of Shadows, which is currently 99c on pre-order until publication on October 1st, when it reverts to full price. It is available on all the Amazons, Kobo, Nook and other places. https://www.amazon.com/dp/B07H9LNSR1/ .

Keys to the kingdom 19 September 2018
I am actually loving this story so much that I am hard pushed to find the right words of praise for this series. As a silly mistake on my behalf when I first found the books) I read the first 3 in reverse, so now I really loved learning how it all started. I was not disappointed! Arthur’s snooping into Shadow’s past via the Archive made me want to read on past the point where I really should be putting down the book and it flows in such a lovely way, that the reference to all the alien tech does not clog up the understanding with over-techinical definitions or super sci-fy information. It’s imaginative and unique. It is simply a joy to have discovered a new fabulous author and I cannot wait for the next book to be released! If you are thinking ‘maybe’ – just don’t! Buy it and read it! You won’t be sorry!
